App-based Protein Support for Older Adults; Coaching Towards Healthy Ageing

Enrolling by invitation · Not applicable

Conditions studied: Dietary Protein Intake

In brief

Rationale: Sufficient dietary protein intake helps to preserve muscle mass and strength and is a key factor in healthy ageing. Achieving an increased protein intake with regular food products has shown to be a challenge for many older adults. Applying behavioural change techniques may facilitate a more sustained improvement in protein consumption over time. Objective: To investigate whether a nutritional app intervention can increase the protein intake (with the goal of 1.2 g/kg body weight/day) of older adults, using readily available food products. Secondary and tertiary objective include the effects of the intervention on body composition and muscle strength and long-term effects on protein intake.
